Eff 109444-lf 1/2 Inch Pex Brass No Lead Tee Fitting U9444-LF 5423-011 PXT03LF PXTE0012-NL

Product Description

The EFF 109444-lf is a 1/2 inch no-lead brass PEX tee fitting designed for residential and commercial plumbing systems. It connects three 1/2 inch PEX lines in a tee configuration, making it a practical choice for branching water supply lines. Plumbers and pipefitters rely on tee fittings like this one when splitting a single supply line into two directions or joining three runs of PEX tubing at a single point. The 109444-lf is built from lead-free brass, which meets the requirements of modern plumbing codes for potable water applications. Lead-free compliance is critical in drinking water systems, and this fitting satisfies those standards for safe water delivery. Brass construction gives this fitting excellent durability, corrosion resistance, and a long service life in both hot and cold water lines. PEX tubing has become one of the most widely used materials in modern plumbing installations. It is flexible, freeze-resistant, and easier to route through walls and floors compared to rigid pipe. A reliable brass tee fitting is essential to maintain watertight connections and consistent flow throughout a PEX system. The 109444-lf accepts PEX on all three ports, so installers can use it in any configuration where three PEX lines meet. This fitting is commonly used in new construction, remodels, and repair work. It works well in radiant heating systems, domestic water distribution, and fire suppression rough-in applications. The compact design of a 1/2 inch tee fits tight spaces and low-clearance installations. Plumbing professionals searching for a no-lead brass PEX tee in the 1/2 inch size will find this fitting a straightforward, code-compliant solution. Cross-reference part numbers include U9444-LF, 5423-011, PXT03LF, and PXTE0012-NL.
